Anyone who has struggled with an arcade claw machine knows that controlling a mechanical arm is not as easy as it looks. Excavator operators face a much harder version of the same problem. They must coordinate several joystick movements to control the machine’s boom, arm, bucket and cab at the same time. Learning those controls […]

A gigantic line of cliffs may once have stretched for thousands of kilometers across ancient North America, helping erase more than a billion years of geological history from rocks now exposed in the Grand Canyon. Scientists led by the University of Southampton in the UK believe this enormous landscape formed about 800 million years ago, […]

A faint gravitational-wave signal spreading across the universe may contain clues about mysterious stars that existed more than 13 billion years ago, according to new research. Scientists from Colgate University have investigated whether some of the earliest supermassive black holes could be responsible for much of the extremely low-frequency gravitational-wave background detected today. Their findings […]

Some of the earliest massive galaxies in the universe may be hiding enormous numbers of small, faint stars, suggesting they contain much more mass than astronomers previously believed. Using the James Webb Space Telescope (JWST), an international team led by researchers at Leiden University studied nine massive galaxies from the early universe. They discovered that […]

A urinary tract infection may make memory problems worse after a traumatic brain injury, according to new research in mice. The study raises an important question about whether a common infection could interfere with the brain’s recovery after an injury. Traumatic brain injury, often shortened to TBI, happens when a blow, fall or other force […]

A compound connected with foods such as pomegranates and walnuts could point scientists toward a new treatment for one of the most stubborn forms of heart failure. Researchers found that urolithin A helped stiff heart tissue relax and reduced several damaging changes linked to the disease. Urolithin A is not simply a nutrient that comes […]

Moving your body is generally good for your health, but new research suggests that all physical activity may not have the same relationship with the aging brain. A huge analysis found that exercise chosen for fun was linked to less dementia, while heavy physical activity at work was linked to more. The research came from […]

Parents often notice differences between their first and second child and wonder whether birth order really matters. A massive new study suggests it may be linked to health in unexpected ways, although the differences are much smaller than many people might imagine. The findings were published in Nature Health. Researchers analysed health records from more […]

A long-running study suggests that chemicals formed during drinking water disinfection may play a role in uterine cancer risk. Scientists tracked more than 53,000 California teachers and school administrators for nearly two decades and found that women exposed to higher levels of certain water treatment byproducts were more likely to develop uterine cancer. The findings […]
